When Should I Replace My

Filter Cartridge Element?

Pool & Spa filter cartridge elements clog up over time due to oils, dirt, bacteria, algae, and other micro-organisms that adhere to the cartridge elements. Pool and Spa filter cartridges do not have a specific life span and can vary widely depending on bather loads, natural elements, chemical balances and proper cleaning methodology. Each time you clean the cartridge you need to inspect it carefully for remaining dirt or debris.

Reasons that may indicate the need for a new filter cartridge:

1. Filter cartridges are made of a fibrous material, generally reinforced polyester, which gradually wears and loosens becoming more porous over time.  Look for small tears in the media material. If small tears or holes are present, this allows larger particles to pass through the filter and back into the pool or spa water. This lessens the effectiveness of pool or spa sanitizers which will cause more chemical expense to maintain proper sanitation.  If tears or holes are present, discard the filter and replace it with a new one.

2. The ends caps have become brittle, cracked or discoloured.

3. You notice that you have to clean the filter cartridge more often than normal or you seem to be spending more money than normal on chemicals. This is a major indicator that it may be time to replace the cartridge element.

4. The water flow rate has been reduced due to built-up debris in the element that cannot be cleaned, or if the water flow rate is still low after cleaning your cartridge.

5. If the pressure on your pool filter remains or climbs back up quickly (within two or three days) over normal operating pressure after you have cleaned the cartridge then it is time for a new cartridge.

6. The centre core (if applicable) of the cartridge is misshaped, collapsed, separated from the media or any combination of these, then it is time to replace your cartridge filter.

If any of the above are present, it is highly recommended that you discard your old or damaged filter cartridge and replace it with a new one.

 

NOTE: It is always a good idea to keep a backup filter hand. Then, while you are cleaning your current cartridge you can put the backup cartridge in the pool or spa. This can be very beneficial! If you detect a problem with your filter cartridge you have a backup available immediately. 

 

How To Identify Your

Cartridge Filter Element

Measure the length and outside diameter in millimetres, and identify the top and bottom endcap style. Certain styles of endcap (i.e. open, female thread etc.) may require an inside diameter measurement as well.

Find the length measurement in column 2 of the chart below. Then find the length with the matching outside diameter and endcaps. Once you have found the element you require, click on model name in column 1 to go to that product page.

You may get multiple elements with the same measurements - the difference will be the amount of pleats in the element. More pleats increase the surface area giving increased filtering capacity. Most cartridge filters have a number in the model name which signifies the surface are in square feet i.e. 'Waterco Opal 90' has a surface area of 90 square feet.
